RAZOR-SHARPENER.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed February 6, 1914. Serial No. 816,961.

7 '0 all whom it may concern:

Be it known that we, HOWARD A. DAvn) and VILLIAM J. ANDERSEN, citizens of the United States, residing at East Moline, in the county of Rock Island, State of Illinois, have invented certain new and useful Improvements in Razor-Sharpeners; and we do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in devices for sharpening razor blades or the like, and has for its object to so construct a device of this character in such a manner that the blade will be reciprocated and subjected to the action of a pair of sharpening disks rotating in opposite directions.

A further object of the invention is to provide a device, of this character so constructed that the means for rotating the sharpening disk will also serve to reciprocate the blade to be sharpened.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the device. Fig. 2 is an end view. Fig. 3 is an end view of the device opposite to Fig. 2. Fig. 4 is a sectional view on line 44 of Fig. 1. Fig. 5 1s a similar view on line 55 of Fig. 1. r

Fig. 6 is a top plan view of the device.

Referring to the drawing, the numeral 1 V designates a base which supports end plates 2, said end plates having their upper edges termlnating 1I1 reduced extensions 3 Which are provided with bearings 1 for slidably:

supporting the bar 5, said bar being reccannot rotate, it being of course understood that the bearings are rectangular in shape.

The end plates 2 are provided with bearings 6 which receive the boxes 7, said boxes serving to rotatably support the ends of the shafts 8, said shafts being formed from sections 9 and 10 so that the same can be readily engaged with the boxes 7. The sections 9 and 10 of the shafts are connected by the couplings 11. The boxes 7 are spaced apart and are disposed in horizontal alinement,

said boxes being connected by the coil springs 12 which serve to hold the peripheries of the sharpening disks 13 in yielding engagement. The peripheries of the disks 13 are provided with leather bands 14, or any other material desired.

Journaled in the end plates 2 is a drive shaft 15, one end of which is provided with a double grooved pulley 16 for engagement by the belts 17 and 18 which are trained aroundthe grooved pulleys 19 fixed to the ends of the shafts S, the belt 18 being twisted so that the shafts 8 will rotate in opposite directions. The other end of the shaft 15 has fixed thereto a beveled gear 20, which meshes with the similar gear 21 fixed to the vertical shaft 22 which is suitably supported adjacent one of the end plates 2. The upper end of the shaft 22 has fixed thereto a disk 23 which is provided with an eccentrieally mounted pin 24 which is pivotally engaged by the outer end of the link 25, said link having its inner end terminating in a vertical projection 26 which pivotally engages the bar 5 so that when rotary movement is imparted to the shaft 22 said bar will be reciprocated.

The bar 5 is provided with a clamp 27 for engaging the blades 28, the cutting edges of which are yieldably engaged by the periphery of the sharpening disks 13, whereby when the disks are rotating and the bar is reciprocating the blades will be efiectually sharpened.

A crank handle 29 is fixed to the shaft 15 and when grasped and rotated will impart rotary movement to the shaft 22 for recipro eating the bar 5 as well as rotating the shaft 8 and shaft 15.

What is claimed is A razor grinding machine comprising a base, plates supported in spaced relation thereon, spaced boxes yieldably and slidably associated with the plates, horizontal shafts having their ends journaled in the boxes, abrasive disks fixed to the shafts, said plates having extensions on their upper edges and provided with guides, a bar having its ends slidably engaged'in the guides, a vertical shaft adjacent one of the plates, a horizontally disposed disk fixed to the upper end thereof, a link having its outer end eccentrically connected to the disk, a projection carried by the inner end of the link nd pivotally engagedwith the bar, a razor blade clamp carried by the bar, means for simul- In testimony whereof, we affix our signataneously rotating the horizontal shafts and tures in presence of two Witnesses.
